Is Forma Visuals a separate subscription?
No. Forma Visuals is built on the chart and vector-graphics oracles, and every plan can call both, at one credit ($0.01) per answer.

Charts and figures you can stand behind.
Forma Visuals turns a plain description into a chart of your values or a figure of what you describe, checked against named, versioned rules before you see it. For analysts, writers, researchers and educators.

Where you already work.
Agents call it over MCP at https://mcp.formalogic.io/mcp, code calls it over HTTP, and people use the console.
What do I get back?
Source in the format you choose: a Vega-Lite, Plotly, ECharts or Chart.js spec or a gnuplot script for charts, and TikZ, MetaPost or PiCTeX source for figures. Each valid answer carries the version of the rules it passed.
What happens when a request cannot pass?
You get a plain no and the reason, not something plausible and wrong. An invalid verdict costs a credit like a valid one; a failure on our side never does.
Where can I use it?
In Claude, ChatGPT, Cursor, VS Code, Windsurf and Codex over MCP, from code over HTTP, and in the console.
